And yes - I know that countless vegans eat 2500-3500 calories - I witnessed it myself with people in my vicinity who went on the vegan diet. 5000 calories and still hungry - go vegan!
I was wondering about how you reached that number as well. If it's true it most probably means that these vegans are also eating a lot of vegan junk food. Can you give us a summary of what they eat on a daily basis?
As far as hunger goes, during the 2019 summer I did a 1 month vegan detox and I can honestly say that I was not feeling hungry all the time. I was doing 14-16 hours of fasting in between meals and I was not eating more than 1500 colories per day.
Here is what I observed about myself and others in relation to hunger. When people have time to sit around or keep wandering in the kitchen after doing brainless activities, they are bound to get hungry. The busier you are, the less hungry you feel.
Sometimes, we need to redefine what hunger really is. Most of the time we mistake our body's need for water as a signal for hunger. That's what I noticed about myself and others.
The vegans that you know are most probably loading themselves with a lot of crap if they feel hungry. The more junk food you eat (especially sugar) the hungrier you feel. Avoid junk food for a while, and your taste buds will adapt to natural flavours.
I'm not advocating for any extremes like veganism and carnivore diets, but people need to stop labeling what they are doing and actually start looking if they get their micro and macro nutrients right.
Also the globohomos are more concerned with pushing sugary foods rather than vegan diets. The real devil is chocolate, pies, sugar drinks, etc., that people shove in to their children's throat at an early age and then they wonder why their kids develop nasty diseases before they even hit 20. Absolutely despicable.
If only people stopped attaching excess meaning to their diets we would have a much healthier population.
The last thing that people don't pay attention to is psychology. I've met people who eat a lot of junk on a daily basis and yet they seem very energetic and happy, because they wake up every day and their minds are flooded with feel good chemicals just by thinking of the possibilities in life. Warren Buffet and Donald Trump probably have some of the shittiest diets and yet they are fueled by how good they feel. These are extreme examples, but you get my point. If you wake up in the morning and you have nothing to look forward to, then no matter how good your diet is you will still have problems.
You probably have a purpose in life that you have in mind every time you wake up, but look at how people who are not driven by anything. No matter what they eat, they are like zombies or too restless from anxiety attacks.
